Hello,
I've been lurking for a while, hoping to make some sense of all this...and I could use some help.
I have two children (DD, almost 3YO and a DS, 7). My son was diagnosed on the autistic spectrum when he was very young (14 months), which was a controversial diagnosis at the time. We started DAN! biomedical interventions and dietary changes immediately, and he improved quickly, shedding his diagnosis by age 3. Though he no longer has a spectrum diagnosis, he still has symptoms that look like ADHD, which get dramatically worse for a period of several weeks following ANY insult to his immune system.
We have known since he was 2 that he does not mount antibody responses to P. Strep, or Candida, and has both low IgG and IgA. Three immunologists have dismissed these lab findings as meaningless because he has not had re-current respiratory/ear infections. They all wanted to re-vax, then check titers to see if there was an immune response. I declined these requests, not feeling that safe for my son. All three immunologists would go no further with us unless we re-vaxed.
My son rarely comes down with cold type viruses. He starts to get symptoms of a cold, but then the symptoms just vanish in a day or two...but the behavioral changes still arrive, and last for many weeks. When he gets a fever type virus, he always spikes fevers of 105+ for 3 days, but it can be reduced with Ibuprofen/tepid bath. I'm not sure whether his immune system is over or under active, or both.
What is different about my son, is that he doesn't have the typical symptoms of PANDAS. He doesn't seem to have OCD or anxiety in the way I see it described here, though he does get very ridged in his thinking, demanding that things be a his way. He becomes fixated on his ideas, and melts down if things don't go his way. He also a drunken behavior that comes and goes that I have always associated with yeast. He has to be on a maintenance dose of antifungal medication or he is so loopy he can't function. But even with that, he still has episodes of very strange behavior in which he can't stop laughing and using potty language, and bouncing off the walls/floors, and hitting himself in the face and laughing about it. These sudden episodes can last 5 to 45 minutes, and then he's normal again.
My daughter is more typical, but also develops loopy/temperamental behavior and sleep disturbances for several weeks following viral infection. She often needs anti-fungal and antibiotics (Flagyl) to return to normal.
I have sent my son's blood to Dr. C, but haven't rec'd results yet. He wasn't in an exacerbation at the time, so I don't know if that will be conclusive. His doctor ran DNASE-B and a bunch of other tests, which were normal. I would love to know your thoughts. Is there anyone out there with a case like this? And if so, did what therapies helped?
Also, I read that if you have low or no IgA, you are not a candidate for IVIG because of possible autoimmune response. Since my son has low IgA, could he still have IVIG. Is he a good candidate?
Thanks for your help!
